Sayang, kesian you lagi kena sakit macam tu after 3 months, do have a chat with your gynae or the clinic nurse about the extra tissue, sebab sometimes it needs proper checking to make sure it's healing the way it should, ye? In the meantime, be very gentle when cleaning that area, maybe use warm water je and pat dry softly, jangan kena gesel. Hoping it settles down soon for you!
